 Disassembly Procedure

 Prior to Disassembly and Reassembly

WARNING

  Before disassembling and reassembling the pump, be sure that the power 

supply (i.e. circuit breaker) is disconnected, and remove the cabtyre 

cable from the outlet. Do not perform this operation with a wet hand, 

which could cause electrical shock. To prevent serious accidents, do not 

perform an activation test (to check the rotation of the impeller) during 

disassembly and reassembly.

This section explains the disassembly and reassembly processes that are involved up to 

the replacement of the impeller itself. Operations involving the disassembly and reassem-

bly of the sealing portion (i.e. mechanical seal) and of the motor require a specialized 

facility including vacuum and electrical test equipment. For these operations, contact the 

dealer where this equipment was purchased, or the Tsurumi sales office in your area.

 Suction Inlet

(1) Place the pump sideways, and 

thoroughly wash the inside of 

the pump through the suction 

inlet.

 Inside the Pump

(1) If the inside of the pump is 

clogged with debris, remove 

the bottom pump casing and 

the nine screws at the bottom 

of the strainer by using a 

Philips screwdriver.

(2) Remove the bottom pump 

casing and the packing 

together, and use your hands 

to remove the debris from the 

impeller.

(3) After removing the debris, 

check that the impeller spins 

smoothly by turning it with 

your hand.

(4) If the impeller does not spin 

smoothly, remove the cross 

recessed head truss screw 

with flat washer, and remove 

the spring washer with the 

impeller, in order to remove 

the debris from behind the 

impeller.

WARNING

  Never disassemble areas other than those that are indicated above. Improper 

disassembly may cause the pump to malfunction and lead to current leakage, 

electrical shock, or fire.

 Reassembly Procedure

(1) Turn the pump body upside down, insert the air valve, and install the packing on the 

pump body. While installing the packing, align its position properly with the pump 

body.

(2) Then, place the bottom pump casing and the strainer, and tighten the nine screws with 

a Philips screwdriver.
